Poisoning by oth systemic anti-infect/parasit, acc, sequela

This code signifies a long-term complication or residual effect resulting from an accidental overdose or adverse reaction to a systemic anti-infective or antiparasitic medication not otherwise specified. The initial poisoning event was unintentional, and the patient is now experiencing a chronic condition directly attributable to that past exposure.

Use this code when documenting a sequela, such as chronic organ damage (e.g., kidney failure, neuropathy) or persistent neurological deficits, that developed as a direct consequence of an accidental poisoning by an anti-infective or antiparasitic agent. This code is appropriate when the acute phase of the poisoning has resolved, and the patient is being treated for the lasting effects.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past accidental poisoning by a systemic anti-infective or antiparasitic.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
